Just in case that time a guy ate another guy's face didn't clue you in to the fact that you should not do bath salts, here is a NSFW video from the US Navy to expound a little further on that notion.

If you do bath salts, you might not eat somebody' face, but you might punch your girlfriend in the face at a bowling alley. Or your roommate could turn into a demon. Or you might listen to dubstep. Basically, if you do bath salts, you're gonna have a bad time. Don't do drugs.
